Review on Clean Easy PC 86562 Easyclean Duster by Brent Borseth

I bought this to clean wooden blinds in the doors. The website says it cleans "Blind Size Blinds," and if you remove the chenille and remove the rubber cover, you might be able to stick your bare fingers between the mini blinds, but that won't work if you're also using chenille. THEN I found out that even though I ordered this from Revain and Revain fulfilled and shipped the order, it was NON-REFUNDABLE. Very dissatisfied and feel cheated by a useless $22 product.
